I love this umbrella!! It is doing its job when it comes to the bright sun making my room so hot. So, my room is where the patio is in my apartment. And I can't do so much to help block the sun without breaking some kind of rule. But i can have a patio umbrella and especially in the hot so cal weather my room would get so hot. Now, its completely the opposite my room is cool. I love it and so far so good.
